| Sofie 🏳️⚧️ (she/her) | How would I know they actually succeeded? | 09:41:53 |
| Sofie 🏳️⚧️ (she/her) | Sorry for the bad picture btw ;3 | 09:43:19 |
| Sofie 🏳️⚧️ (she/her) | or is this too offtopic for this room again? 😭 | 09:43:39 |
 Arian | I expected nix build .#mypackage —no-fallback to fail if it can’t substitute. But instead it just builds anyway. Bug? | 16:41:12 |
| Arian | The docs say “Lix will fall back to building from source if a binary substitute fails. “ so I expect —no-fallback to disable that. But maybe i am misreading the docs? What does “fails” mean here? Maybe 404 is not a “Failure” ? | 16:44:34 |

 aloisw | Indeed uncached path is not a failure. If you do not want builds that sounds more like the job of max-jobs = 0. | 17:18:20 |
|  QuadRadical (Ping) @ FOSDEM changed their display name from QuadRadical (Ping) to QuadRadical (Ping) @ FOSDEM. | 21:19:04 |
 Winter | once again running into system-units (+ etc maybe) taking a weirdly long time to go from building …system-units.drv to the next (building …etc.drv) while building a NixOS system. anyone else? | 22:35:07 |
| Winter | I’m making very small changes that only affect config files | 22:35:19 |
| Winter | So I don’t think it’s collateral | 22:35:27 |
 raitobezarius | how many drvs in the dependency graph? | 23:36:15 |
| raitobezarius | building the NixOS system on a NixOS system or? | 23:36:24 |
| raitobezarius | aren't you affected by a form of https://github.com/NixOS/nixpkgs/pull/479442 ? | 23:36:53 |
| raitobezarius | also if you rebuild that .drv using --rebuild, are you reproducing that long delay? | 23:37:40 |

| Winter | I tried that, didn’t appear to but I’ll need to do more tests | 01:04:50 |
| Winter | perhaps? 👀 | 01:04:59 |
| Winter | yes (wait, would that matter vs. any other Linux?) | 01:05:11 |
| raitobezarius | other Linux systems may have weird LSM that slow down things | 01:05:28 |
| raitobezarius | or you may have an enterprise software EDR that slow down things | 01:05:35 |
| raitobezarius | * or you may have an enterprise software EDR/security that slow down things | 01:05:40 |
| Winter | gotcha (i don’t, to clarify( | 01:05:48 |
| Winter | * | 01:05:52 |
| Winter | * | 01:05:56 |
| raitobezarius | yeah, just trying to rule out foreign reasons | 01:05:58 |
| Winter | will collect some better timings tomorrow | 01:06:01 |
| Winter | thanks 🫡 | 01:06:05 |
| raitobezarius | np! | 01:06:09 |
|  dish [Fox/It/She] left the room. | 01:15:41 |
